Abstract

Methods, systems, and devices for implantable node are described. The method may include storing, at an implantable stimulation node, a set of stimulation profiles in a memory during a configuration phase. The method may also include receiving a stimulation command corresponding to a stimulation profile of the set of stimulation profiles during a treatment phase. The method may further include delivering stimulation based at least in part on the stimulation profile corresponding to the received stimulation command. In some cases, the system may include an implantable hub, an implantable sensing node, and a sensing device.
